Abstract :
In this experiment investigating about agricultural sprayers, several methods are used to obtain information. Practically, the experiment is required to calculate the volume of liquid or weedicide mixture required to cover a 1-ha area by using information such as the 5% percentage of concentration of liquid which is 5ml of liquid in a 1 litre bottle and estimation that this sprayer covers 20 km/hr. Therefore, students measure the volume of water flows out through the nozzle by using measuring cylinder for 5 seconds. Data obtained were then used to calculate the volume of liquid or weedicide needed. Sprayers are commonly used on farms to spray pesticides, herbicides, fungicides, and defoliants as a means of crop quality control. Invention of sprayer improves the quality of agriculture. They are easy to operate, maintain and handle and facilitates uniform spread of the chemicals.
